Chronomètre Bleu 39mm Tantalum

The Chronomètre Bleu offers an uncluttered approach to high precision, with irreproachable chronometric proprerties. It is innovative, with a 39 mm case made of Tantalum, a rare dark grey metal with blue overtones, so named for the “Torment of Tantalus” in reference to the Greek mythology. Tantalum is a metal rarely used in watchmaking because it is very hard and difficult to fashion (its fusion temperature is 3016° and its density 16.65 kg/cm3). It is also valued for its extremely high resistance to corrosion and wear, and its bio compatibility.

The Blue chrome dial, which perfectly complements the colour of the case, has been redesigned with the latest trends in mind, and features cream-coloured hands and large Arabic numerals.

The Chronomètre Bleu’s 18K Rose Gold mechanical movement with manual winding oscillates at 21,600 vibrations per hour. Twin barrels, in the classic configuration of precision watches, work in parallel to deliver stable power for most of the watch’s 56-hour autonomy. The F.P.Journe freesprung chronometer balance, with inertia adjustment via four opposing weights, is dynamically adjusted in six positions.
